## Pick the right model

**Wan 2-7 Edit-Video** — `wan-ai/wan-2-7/edit-video` *(default)*

> Prompt-driven video edit; accepts spatial extension language ("extend the canvas to 16:9 by adding matching environment on the left and right"). Wide enough quality for social and most internal uses.

> Pick for: aspect-ratio swap (vertical ↔ horizontal), social-cuts, uncrop where seam quality is acceptable.

> Avoid for: hero ad delivery with strict seam-quality requirements — use a ComfyUI outpainting workflow.

For broader video edit see [`video-edit`](https://www.skills.sh/agentspace-so/runcomfy-agent-skills/video-edit).
